Based on the battery charging and discharging regulator (BCDR) in spacecraft power conditioning unit application, a bidirectional DC-DC converter BCDR with high direction-changing frequency is proposed in this paper, including the Weinberg-buck bidirectional DC-DC topology and the corresponding bidirectional control. Additionally, the test on the BCDR prototype shows that BCDR parallel modules could...
This paper proposes a novel electrical power supply system architecture (power conditioning and processing unit, PCPU) for high-power all-electric propulsion spacecraft platform with high-voltage power bus (HVBUS) powering thrusters and regulated power bus (VBUS) powering onboard payloads, respectively. The design principle of function modules in PCPU has been analyzed. Besides, the test on electrical...
